> So, the other possibility is that authors deliberately reject the legal system per se. The reasoning can go as follows: I do care about my peers using my software. I don't give a damn about whether the lawyers and mega-corporations they work for use it. So, if you are like me and you don't care about all the intellectual property antics, here's my project, feel free to use it. If you are the kind of moron who wants to have their legal ass covered, go screw yourself.

I totally buy the idea that at least some users who upload source to GitHub without a license feel that way. I have slightly different priorities (creating software that is used is more important to me than avoiding the copyright antics) but I'm pretty sympathetic to that sentiment.

The problem with expressing that sentiment by not licensing your software is that it doesn't express that sentiment at all, especially on GitHub. GitHub's terms of use require that public repositories contain only open source code, so there's an argument to be made that uploading your code to a public repo on GitHub implies an open source license.

If you really want to make a civilly-disobedient statement rejecting the idea of licenses, I'd do so with something like the Forget Users License[1].

EDIT: I'm not a lawyer and would love to make this more lawyer-y. Suggested improvements to the license are welcome.
